This form must surely be considered a variety of A. moron., of 

 which it partakes the very peculiar radiating structure of the processi- 

 ferous sectors. On the other hand the sectors without processes do not 

 possess the deltoid depression mentioned and figured by G re ville, but 

 are spotted on a ground of decussate striæ. 



KKt (only one specimen met with).
